Abstract
In October 2024, a large-scale blight was found on tender shoots (young green shoots) of Juniperus formosana in Kaili City, Guizhou Province, China. The pathogen was isolated and purified from the diseased tissues by the tissue isolation technique. Through ITS identification and microscopic examination, the pathogen was determined to be Fusarium avenaceum. This is the first discovery in China that the blight on Juniperus formosana is caused by Fusarium avenaceum.
